TECHNICAL FIELD

[0001] The present invention relates to a binding-off process to preventloosening of loops at an edge of a fabric knitted by a knitting machineon the flat knitting machine comprising at least a pair of front andback needle beds having a number of knitting needles fitted in needlegrooves. The present invention also relates to a knitted fabric thusbound off and to a CAD device used for the binding off process.

BACKGROUND ART

[0002] A binding-off process for preventing loosening of loops in thefinal course (final row of needle loops) at an end of a fabric knittedby a flat knitting machine is known. In the binding-off process, a loopin the final course of the knitted fabric is laid over the next to forma double loop and a loop of the next course is formed at the doubleloop. This knitting is repeated from one end of the fabric to the otherend thereof to clear the loops of the final course of the knitted fabricfrom the needles in sequence. When a two-layered fabric comprising frontand back parts is knitted in overlapping relation in back and front andalso the loops in the final course are bound off by using the front andback needle beds, the both fabrics are joined together at an end thereofon the side on which the knitting is finished. For example, when thisbinding-off process is used to join together front and back bodies of asweater along a shoulder line, the need of a sewing process after theknitting can be eliminated.

[0003] The applicant previously made the proposals for the binding-offprocess to prevent loosening of loops while joining together two fabricsknitted in overlapping relation in back and front, like front and backbodies of a sweater, in Japanese Laid-open (Unexamined) PatentPublications No. Hei 8 (1996)-337946. Japanese Laid-open (Unexamined)Patent Publication No. 8 (1996)-337946 discloses the binding-off processwherein after a loop of a front knitted fabric and a loop of a backknitted fabric, placed opposite, are each transferred to the needles onthe opposite needle beds for a while, the loop of the back knittedfabric is laid over the loop of the front knitted fabric to form adouble loop and then a binding-off loop continuous to the double loop isformed. This knitting is repeatedly performed to bind off the loops ofthe front and back knitted fabrics. In this binding-off process, asingle row of binding-off loops are formed along the joints of the frontand back knitted fabrics. It is to be noted that the terminology of “rowof binding-off loops” used in this specification is intended to mean achain stitch formed in the binding-off process.

[0004] In the binding-off process of Japanese Laid-open (Unexamined)Patent Publication No. Hei 8 (1996)-337946, only a single row ofbinding-off loops are formed and the number of loops in the single rowof binding-off loops formed in the binding-off process is identical withthe number of wale in the binding-off region.

[0005] The present invention relates to a binding-off process to preventloosening of loops at an edge of a fabric knitted and discloses a novelbinding-off process that can reinforce a binding-off section and alsocan suppress elongation of the binding-off section; a bound off fabric;and a CAD device for binding off process.

[0006] For providing further improvements, the present inventionprovides a binding-off process which is performed by using a flatknitting machine comprising (i) at least a pair of first and secondneedle beds, which have a number of needles, respectively, and areplaced opposite in front and back, between which a needle bed gap isdefined, and at least either of which is movable slidably transversely,and (ii) at least one yarn feeder for feeding a yarn to the needles ofthe first needle bed and the second needle bed, and in which theknitting that loops of rows of binding-off loops are formed with respectto a final course of a knitted fabric, so as to be continuous from aloop in the final course, and a newly formed loop of each row ofbinding-off loops is laid over a loop next to the loop in the finalcourse, to form a double loop is repeated from one end of a binding-offregion toward the other end thereof, to prevent loosening of loops inthe final course, wherein n number of rows of binding-off loops areformed, starting from a plurality of loops in the final course in thebinding-off region, and wherein when loops of the rows of binding-offloops are laid over loops in the final course in the process of thebinding-off process, the loops of the rows of the binding-off loops arelaid over loops in the final course located n-th wale forward of theloops, respectively, with respect to the binding-off proceedingdirection. According to this construction of the present invention, therows of binding-off loops are formed, starting from a plurality of loopsin the final course in the binding-off region, and the knitting that aloop of each row of binding-off loops is laid over a loop in the finalcourse located n-th wale forward of the loop with respect to thebinding-off proceeding direction is repeatedly performed to form nnumber of rows of binding-off loops. The rows of binding-off loops maybe formed in parallel with each other or may be formed in sequence insuch a manner that after any one of rows of binding-off loops is formedsequentially to the end, the other row of binding-off loops is formed.This binding-off process can provide a plurality of rows of binding-offloops for the binding-off section and, as a result of this, thebinding-off region can be reinforced and the elongation can besuppressed. Further, lengths of the rows of binding-off loops can befreely adjusted by adjusting the number of rows of binding-off loopsformed, length of the loop formed, and the number of times to knit therow of binding-off loops formed in the binding-off process.

BEST MODE FOR CARRYING OUT THE INVENTION

[0018] An example of the present invention will be described below withreference to the accompanying drawing figures: 1 showing knittingcourses; 2 showing loops; and 3. A binding-off process of a final courseof a plain knit is taken as an example. FIG. 2 shows the loops in therest of the final course only. Alphabetical letters represent needles onwhich loops were retained in the course 0 of FIG. 1. In the following,the binding-off process of the invention will be explained with anexample wherein a two-bed flat knitting machine comprising a pair offront and back needle beds confronting each other across a needle bedgap and having a number of needles arranged on tops thereof, the backneedle bed being formed to be movable laterally relative to the frontneedle bed, is used in the condition in which all needles are used toknit a fabric, without any empty needles for loop transfer beingarranged between needles for loop forming. The binding-off process ofthe invention may be practically worked by using a four-bed flatknitting machine having a pair of upper front and back needle beds whichare arranged over the lower needle beds and on which loop transfermembers are arrange in the same pitch as the lower needle beds. Also,when the two-bed flat knitting machine is used, a half gauge knittingmay be selected in which front and back knitted fabrics are knitted withalternate needles or with odd needles and even needles, respectively, sothat when the front knitted fabric is knitted, the loops of the backknitted fabric can all be retained by the needles of the back needlebed, while on the other hand, when the back knitted fabric is knitted,the loops of the front knitted fabric can all be retained by the needlesof the front needle bed. In this half gauge knitting, since the frontknitted fabric is associated with the front needle bed and the backknitted fabric is associated with the back needle bed, the empty needlesfor loop transfer can always be reserved on the opposed needle beds.This can allow the front knitted fabric and the back knitted fabric tobe knitted in the form of front stitches and back stitches. The halfgauge knitting may be combined with the racking operation of the frontand back needle beds to provide the lateral shift.

[0019] The course 0 of FIG. 1 shows the state before the start of thebinding-off process. The loops of the final course of a plain knittedfabric are retained by the needles B-J of the course 0. The loopsretained by the needles B-J are bound off from the left end toward theright end. This direction of the loops being bound off from left toright is defined as “the binding-off proceeding direction” in thefollowing description. In the course 1, a loop 3 of a first row ofbinding-off loops is formed by feeding a yarn to the needle B of thefront needle bed via a yarn feeder 1, starting from a loop 2 located ata side end of a binding-off region. In the next course 2, the loop 3 istransferred to the needle b of the back needle bed. In the course 3,after the yarn feeder 1 is moved to a location not to cause anobstruction of the knitting, the loop 3 is transferred to the needle Dof the front needle bed and laid over a loop 4 of the final courselocated two wale forward of the loop 2 with respect to the binding-offproceeding direction. In the course 4, a loop 6 of a second row ofbinding-off loops is formed by feeding the yarn to the needle C of thefront needle bed, starting from a loop 5 of the final course. In thecourse 5, the loop 6 is transferred to a needle c of the back needlebed. In the course 6, the loop 6 is transferred to a needle E of thefront needle bed and laid over a loop 7 of the final course located twowale forward of the loop 6 with respect to the binding-off proceedingdirection. Subsequently, the loop to be knitted in each of the courses1-6 is transferred forward with respect to the binding-off proceedingdirection and the newly formed loop of each row of binding-off loops islaid over a loop of the final course to form a double loop. Then, theyarn is fed to that double loop, to form a loop of the next course. Thisknitting is repeatedly performed to bind off the loops in the finalcourse sequentially.

[0020] As shown in FIGS. 2 and 3, the two rows of binding-off loops,comprising the first row of binding-off loops 11 which is formed in sucha manner that a loop formed with every other needle B, D, F, . . . islaid over the next and the second row of binding-off loops 12 which isformed in such a manner that a loop formed with every other needle C, E,G, . . . is laid over the next, are formed in the knitted fabric boundoff in the bonding-off process of the first embodiment. These two rowsof the binding-off loops are formed in parallel and also the number ofloops in each row of binding-off loops is reduced to half as many as thenumber of wale in the binding-off region, as compared with thebinding-off process wherein the number of binding-off loops are formedto be identical with the number of wale in the binding-off region. Inthis embodiment, since the two rows of binding-off loops are formed, thebinding-off section can be reinforced, as compared with the binding-offprocess where only a single row of binding-off loops is formed.

[0021] Now, reference will be made of the second embodiment withreference to FIGS. 4-7, taking the process of binding off a shoulderportion of a sweater 21 of FIG. 4 as an example. FIG. 4 shows thefinished state of the sweater 21 to be knitted. The sweater 21 comprisesa tubular body 22 comprising a front body 22 a and a back body 22 bwhich are knitted in an overlapped manner in front and back andconnected to each other at both ends thereof, and left and right tubularsleeves 23, 24 joined to the tubular body 22 from underarms 25 a, 25 bto shoulders 26 ta, 26 b. The knitting of the body 22 starts at its hem27 and the knitting of the sleeves 23, 24 start at their cuffs 28, 29,and the body 22 and the left and right sleeves 23, 24 are each knittedin a tubular form up to underarms 25, separately. The sleeves 23, 24 andthe body 22 are joined together at the underarms 25 by knitting the body22 in the state in which the loops in the final course of each sleeve23, 24 are overlapped with the loops of the body 22 at their side ends.After completion of the joining of the sleeves 23, 24 to the body 22,the front body 22 a and the back body 22 b are joined together at theshoulder 26 in the binding-off process. As the knitting processes beforethe start of the binding-off process of the shoulder portions 26 a, 26 bare already known, the binding-off process from the point at which thejoining of the left and right sleeves 23, 24 to the body 22 is ended andthe binding-off process of the shoulder 26 starts will be described inthis embodiment. Also, although the left and right shoulder portions 26a, 26 b sandwiching a collar opening 30 therebetween are both bound offin the actual knitting, only the knitting of the right shoulder portion26 a of the sweater to be bound off is described, for convenience ofexplanation. In this embodiment, the binding-off process starts from anend of the shoulder toward the collar opening 30.

[0022] In the course 0 of FIG. 5, the loops of a front shoulder portionof the front body 22 a, which is formed into the right shoulder portion26 a in the sequent binding-off process, are retained by the needles B-Gof the front needle bed and the loops of a back shoulder portion of theback body 22 b are retained by the needles b-j of the back needle bed.An end of the shoulder is located on the left-hand side as viewed inFIG. 5 and the needles H-J of the front needle bed are for the collaropening 30. In the course 1, a loop 41 located at a side end of the backshoulder portion is transferred to a position outside of a loop 42located at a side end of the front shoulder portion retained by theneedle B of the front needle bed. In the course 2, the loop 42 at theside end of the front shoulder portion is transferred to the needle b ofthe back needle bed which turned to an empty needle. In the course 3,the loop 41 located at the side end of the back shoulder portion istransferred back to the needle b of the back needle bed and laid overthe loop 42 at the side end of the front shoulder portion to form adouble loop. In the course 4, a loop 44 of a first row of binding-offloops is formed by feeding a yarn to the needle b via a yarn feeder 43,starting from the double loop formed by the loops at the side ends ofthe front and back shoulder points. In the course 5, after the yarnfeeder 43 is moved to a location not to cause an obstruction of theknitting, the newly formed loop 44 is transferred to the needle D of thefront needle bed and laid over a loop 45 of the front shoulder portion.In the course 6, a loop 46 retained by the needle c located forward ofthe loop 41 transferred in the course 1 with respect to the binding-offprocess proceeding direction is transferred to the needle B of the frontneedle bed. In the course 7, a loop 47 retained by the needle C of thefront needle bed is transferred to the empty needle c of the back needlebed. In the course 8, the loop 46 of the beck shoulder portion as wastransferred to the needle B of the front needle bed is transferred tothe needle c and is laid over the loop 47 of the front shoulder portionto form a double loop thereat. In the course 9, a loop 48 of a secondrow of binding-off loops is formed by feeding the yarn to the needle cvia the yarn feeder 44, starting from that double loop. In the course10, after the yarn feeder 44 is moved, the newly formed loop 48 istransferred to the needle E of the front needle bed and laid over a loop49 of the binding-off loops in the final course. Subsequently, thisknitting is repeatedly performed until the loops are all bound off,while the loops to be knitted in each of the courses 1-10 aresequentially transferred forward with respect to the binding-offproceeding direction.

[0023] The knitted fabric bound off in the binding-off process of thesecond embodiment is shown in FIG. 7. The newly formed loop 44 on thedouble loop, which is formed from the loop 42 retained by the needle Band the loop 41 retained by the needle b in the course 0, is laid overthe loops 45, 51 retained by the needles D and d, respectively.Likewise, the newly formed loop 48 on the double loop, which is formedfrom the loops 46, 47 retained by the needles C and c, respectively, islaid over the loops 49, 50 retained by the needles E and e,respectively. In the knitted fabric subjected to the binding-off processof the second embodiment, two rows of binding-off loops are formed,comprising a first row of binding-off loops 52 which is formed by layinga loop formed with every other needle B b, D d, F f, . . . over the nextand a second row of binding-off loops 53 which is formed by laying aloop formed with every other needle C c, E e, G g, . . . over the next.The first row of binding-off loops 52 and the second row of binding-offloops 53 are both formed to have the number of loops half of the numberof wale in the binding-off region. In the second embodiment, the loopsin the final course of the front shoulder portion are retained on theback needle bed and the loops in the final course of the back shoulderportion are retained on the first needle bed, followed by transferenceof a loop in the final course of the front shoulder portion to theopposed needle bed so that the loop in the final course of the frontshoulder portion and the loop in the final course of the back shoulderportion can be overlapped with each other. As a result of this, theloops in the final course of the back shoulder portion are twistedbefore they are laid over the loops of the front shoulder portion. As aresult of this, the binding-off section can be prevented from beingprojected. In addition, since the loops 44, 48 of the row of binding-offloops go into hiding under the loops of the other row of binding-offloops and the loops in the final course 51, 52, 50, 49, the loops of therows of binding-off loops different in orientation of wale from eachother are prevented from coming out to the front side of the knittedfabric. As a result of this, a good-looking line of loops can be formed.As the details on the reason that the binding-off section is preventedfrom being projected and on the reason that the loops of the row ofbinding-off loops go into hiding under the knitted fabric are discussedin Japanese Laid-open (Unexamined) Patent Publication No. Hei8(1996)-337946, the description thereon is omitted herein. As mentionedabove, in the second embodiment, two rows of binding-off loops areformed and accordingly the number of loops in each row of binding-offloops is reduced to half, as compared with the binding-off processwherein the number of binding-off loops in each row of binding-off loopsare formed to be identical with the number of wale in the binding-offregion. Hence, even when a line of bonding-off loops extendshorizontally, like the sweater 21 of FIG. 4, so that there is no coursedifference between the loops in the final course connected by the loopsof the rows of binding-off loops, the loops of the rows of binding-offloops can be prevented from becoming larger than the space between theadjoining loops of the final course by increasing the number of loops inthe row of binding-off loops. As a result of this, the row ofbinding-off loops can be prevented from being loosened to make thebinding-off section odd-shaped.

[0024] As mentioned above, according to the present invention, length ofthe row of binding-off loops can be freely adjusted by adjusting thenumber of rows of binding-off loops formed, length of the loop formed,and the number of times to knit the row of binding-off loops formed inthe binding-off process. For example, as the number of rows ofbinding-off loops increase, the reinforcement of the binding-off sectionincrease. When the number of times to knit the row of binding-off loopsformed in the binding-off process is reduced to reduce the number ofloops of the row of binding-off loops, the knitted fabric whose knittingwidth is shrunk in the binding-off section can be knitted. Although theembodiments have been described above, taking the binding-off processfor the section where the line of binding-off loops extends horizontallyas an example, the binding-off process of the present invention may beapplied to other sections as well, without limited to the section wherethe line of binding-off loops extending horizontally. Also, although thebinding-off process wherein two rows of binding-off loops are formed hasbeen described in the embodiments above, three or more rows ofbinding-off loops may be formed, depending on the material quality ofthe knitting yarn used for the knitting and on the stitch quality ordensity of the loop formed. Supposing that the loops in the row ofbinding-off loops and the loops in the final course are overlapped witheach other in the proportion of one to one, the number of loops per rowof binding-off loops can be reduced by increasing the number of rows ofbinding-off loops. In the case where three rows of binding-off loops areformed, a loop in the row of binding-off loops is laid over a loop inthe final course located three wale forward of that loop with respect tothe binding-off proceeding direction. In the case where four rows ofbinding-off loops are formed, a loop in the row of binding-off loops islaid over a loop in the final course located four wale forward of thatloop. Also, although the embodiments wherein whenever one loop of therow of binding-off loops is formed, the one loop is laid over a loop inthe final course have been described above, whenever two or more loopsof the row of binding-off loops are formed, those two loops may be laidover loops in the final course. In addition, a plurality of yarn feedersmay be used in the binding-off process so that the individual rows ofbinding-off loops can be formed by their respective yarn feeders.Further, although the first row of binding-off loops and the second rowof binding off loops are formed in parallel in the embodiments mentionedabove, one of the first and second rows of binding-off loops may beformed, first, and, then, the other of the first and second rows ofbinding-off loops may be formed. Furthermore, the binding-off proceedingdirection may be reversed so that for example the first row ofbinding-off loops may be formed sequentially in the rightward directionfrom the left end of the binding-off region to the right end thereof,first, and, then, the second row of binding-off loops may be formedsequentially in the leftward direction from the right end of thebinding-off region to the left end thereof.

[0025] The binding-off process mentioned above is carried out byknitting commands stored in a disc and the like being read by a computerbuilt in the flat knitting machine. The computer of the flat knittingmachine interprets the knitting commands and drives mechanisms of theflat knitting machine in a controllably manner. The principal knittingprocesses including the bonding-off process are stored in the form ofsubroutines in a CAD device for designing a knitted fabric. This type ofCAD device includes the computer and output equipment so that theknitting commands can be written on the disc and the like. The CADdevice stores the principal knitting commands in the form ofsubroutines. The subroutines associated with respective parts of thefabric designed by a user are properly combined with each other,followed by the output of the knitting commands. The knitting commandsinclude the command for the flat knitting machine having the computerbuilt-in to knit the fabric in accordance with the knitting commands.The flat knitting machine is driven under control of the built-incomputer, while also the knitting commands stored in the disc and thelike are read by the built-in computer and are interpreted by the CADdevice, to reproduce a design picture of the fabric designed on the CADdevice by the user.
